SOLE-EDGE TRIMMING AND FINISHING TOOL.

To all whom. it may concern:

Be it known that I, Azv'roxio D. FRAS- .COLA, a citizen of the UnitedStates, residing at El Reno, in the county of Canadian and State ofOklahoma, have invented certain new and useful Improvements in Sole-EdgeTrimming and Finishing Tools, of which the following is a specification,reference being had to'the accompanying drawings. 10

This invention is an improved sole edge trimming and finishing tool ofthe class in which there is a revolving cutter, the knives of which arearranged to extend from a rand guide in such manner as to cut the loweredge of the sole,-and a burnishing sleeve having burnishing fingersextending between the knives of the revolving cutter or trimmer, theobject of the invention being to provide an improved tool of thischaracter in which the burnishing sleeve is mounted on the shaft formovement toward and from the rand guide so as to adapt the tool to beused on shoe soles of varying thicknesses, and to provide the burnishingsleeve with improved means for locking the same to the arbor at anydesired adjustment.

The invention consistsin the construction, combination and arrangementof devices hereinafter described and claimed.

In .the accompanying drawing: Figure 1 is a front, end elevation of myimproved tool; Fig. 2 is a side elevation of the same; Fig. 3 is avertical, longitugilinal, sectional view of the same; Fig. 4e is avertical, transverse, sectional view of the sametaken on the planeindicated by the line aa of Fig. 3; Fig. 5 is a similar view taken onthe 'plane indicated by the line bb of Fig. 2'; and Fig. 6 is a detailseetionalview taken on the plane indicated by the .line e u of Fig. 3. r

The shaft on which the; edge trimming tool is mounted is indicated at 1.This shaft is, in practice, mounted in suitable bearings and revolved bysuitable means and usually constitutes a portion of a trimming andburnishing machine. In accordance w1th my invention "the shaft isprovidedin one side with a longitudinal channel 2, on opposite sides ofwhichare series of rack teeth 3. ()n the reduced end 1 of the shaft ismounted the revolving sole trimming cutte' 5, which is rcvol\'ed'by theshaft and comprises the -usual hub t3 and the usual cutter teeth 7 whichare provided witlrcutting edges 8. The trimmer or cutter 5 18 held inplace by the rand guide 9 which is of the usual con- Specification ofLetters Patent.

struction and is secured on the outer end of the shaft by a screw 10.This rand guide enters the crease between the sole and the upper toguide the cutter or trimmer.

The edge burnishing sleeve 11 is mounted on the shaft 1 for longitudinalmovement and provided with the butter teeth 12 which enter the spacesbetween the teeth of the cutter or trimmer. This sleeve is provided onone end'with an annular flange 13. and the said flange is provided, inits outer sitle. with a short slot 14, the axis of which 7 s at rightangles to that of the shaft.

In accordance with my invention I also provide a locking and adjustingcollar 15. which is fitted and longitudinally movable and also partlyrevoluble on the shaft 1. This locking and adjusting collar is'providedat one end with-an annular recess 16 for the reception of the flange 13'of the burnishing sleeve, and the said locking and adj usting collar isconnected to the hufnislr ing lQL\'L by a set screw 17. the, inner endof which engages the slot 14. Ilence. the locking and adjusting collaris connected to the burnishing sleeve for longitudinal movementtherewith and is also adapted to be turned to some extent independentlyof the burnishing sleeve. The locking and adjusting collar'is provided.at one side of its longitudinally of the shaft in order to adjust theburnishing sleeve toward and from the rand guide or shield so as to varythe effective cutting length ot the teeth of the trimmer or cutter. asmay be required, according to the thickness of the sole on which thetool is to operate, and when the burnishing sleeve has been thusadjusted the collar is then turned laterally so as to cause theteeth 18to engage certain of the teeth 3 of the shaft on one side or the otherof the the shatt'and' the tool is revolved. That is to say, it the toolis so constructed that it revolves to the left when in operation, asindicated by the arrow in Fig. 1 of the (lltlVl'lIlgS, the locking andadjusting collar must be turned to the right, and it will be understoodthat the revoluble motion of the tool will keep the locking andadjusting collar locked in place.

It will be understood from the foregoing ioo channel according to thedirection in which i then turn the g v v 1,025,390

- that in order to adjust the burnisher toward those of the shaft, thenmove said collar longitudinally the required distance and same so as toreengage its locking teeth with certain of the locking teeth of theshaft. Such adjustment can be eflected almost instantaneously, and doesnot require the loosening or tightenin of any adjusting screws orother-similar devices.

Having thus described my invention I claim:

1. The combination with the shaft, rand guide and-sole trimmer of a soleedge trimming and finishing tool, an edge burnishing sleeve mounted forlongitudinal movement on the shaft toward and from the rand guide andhaving buffer teeth in the spaces between the teeth of the trimmer, alocking and adjusting collar mounted for longitudinal movement on theshaft, the burnishing sleeve being formed with a transversely extendingslot, and a ,set screw extending through the collar and received in saidslot, whereby the collar is connected to the burnisher for longitudinalmovement therewith and also having partial rotation inde pendentlythereof, the shaft being provided with a longitudinal-channel and withloeking teeth opening into the channeland the collar being provided witha locking tooth adapted for longitudinal movement in said channel and tobe engaged with the locking teeth of the shaft, for the purposespecified.

2. In combination with the shaft, rand guide and sole trimmer of a soleedge trimming and finishing tool, an edge burnishing' sleeve mounted forlongitudinal movement on the shaft toward and from the rand guide andhaving buffer teeth in the spaces bet-ween the teeth of the trimmer, anda locking and adjusting: collar mounted for longitudinal movement on,the shaft and connected to the burnisher for longitudinal movementtherewith and also for partial rotation independently thereof, the saidshaft being provided with a longitudinal channel and with locking teethopening into the channel and the said collar being provided with lookingteeth adapted for longitudinal movement in said channel and to he alsoengaged with locking teeth of the shaft when said collar is partlyrevolved in one direction.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
